BOOK.

SPECIFICATION forming part of Letters Patent No. 227,098, dated May 4,1880.

Application filed 'March 6, 1880, (No model.)

To all whom it may concern:

Be it known that LWILLIAM A. COOKE, Jr., of New York, in the county andState of New York, have invented a new and Improved Memorandum-BookFastener, of which the following is a specification.

My invention relates to an improvement in fastening memorandum -books,tablets, and other blank or printed pages to covers or backs for thesame; and the object of the in vention is to furnish a fastener whichwill confine the memorandum-book securely to the back or cover, and atthe same time will permit it to be quickly and easily attached to anddetached from the cover or back.

The invention consists, first, of a metal fastener attached to the backor cover having a projecting flange, which is bent down so as to presson the book, and a metal rib on the bottom plate for taking hold of thebound end of the book, and thereby prevent it from being drawn out fromthe fastener.

It consists, secondly, in providing the under side of the bound end ofthe book with a groove or recess to receive the metal rib of thefastener.

In the accompanying drawings, Figure 1 represents a plan view of thememorandumbook and fastener with the cover open. Fig. 2 is alongitudinal section of the same, taken on line m a: of Fig. l. Fig. 3represents aplan View of the under side of the memorandum-- book,showing the groove or recess for the rib of the fastener; and Fig. et isa cross-section of Fig. l, taken on line y y, showing also a front viewof the fastener.

Referring to the drawings, A A are the side covers of the book, hingedtogether by a flexible back, B. Adjacent to the iiexible back B, andparallel to the same, is placed the fastener C, composed of a top plate,a, bottom plate, b, and upright portion or plate d, connecting plates ab at one side, made from a single piece of sheet metal.

The fastener is applied to the cover by placing its bottom plate, b,thereon, and fastening it either by rivets passed through it and thecover, or by providing the said plate with prongs, and passing themthrough the cover 5o and clinching them against the opposite side,

or in any other convenient or efficient manner.

yess

d is a rib, formed on the bottom plate of the n fastener by stamping upthe said plate, or in -formed at about the middle of the bottom plate,b.

The top plate, a, has its freeedge bent downward slightly, as shown, forthe purpose of forming a spring-lip, c, which presses on the upper sideof the book just beyond the binding f,- but the lip c may be dispensedwith.

D represents tlie memorandum-book, formed of any number of leaves joinedtogether at one end, which end is covered with the bindine f In thebound end of the book a recess or groove, h, having parallel sides andclosed ends, is formed by cutting through the binding and into thestock, so as to remove a portion of the material. This recess or grooveh is parallel to the end of the book and of about the same length as therib d.

The manner of fastening the book to the cover or back is as follows: Thebook D is turned over parallel to the cover A, and with the groove hdownward. When in this position the bound end of the book is inserted,on one side or the other, between the top and bottom plates, a b, of thefastener, and with f the end close to and parallel with the plate d. Inthis position the book is pushed sidewise across the cover-say in thedirection of the arrow l, Fig. l. The top plate, a, rises or springssufficiently to allow the end to pass freely under it, and also to allowthe said end to rise up on the rib d. The recess h being in line withthe rib d', when the end of the book is inserted between the top andbottom plates 0f the fastener the rib passes into the said recess as thebook is pushed in, and as soon as the inner end of the recess passes thefar end of the rib from the side on which the book is entered the ribdrops into the recess, and the lip e presses down on the book and holdsit in place in the manner shown in Fig. 2.

rIhe pressure of the top plate, a, combined with the hold which the ribtakes on the book by means of its position in the recess h, prevents thebook from slipping out from the fastener in the direction of its length,while the rib d', by its ends abutting against the ends of IOC therecess h, prevents the book from slipping out sidewise. At the sametime, however, the elasticity of the top plate, a, and of the bound endof the book, by yielding when the proper amount of force is exerted,allows the book to be drawn or disconnected from the fastener withoutinjury to it or to the fastener.

The lip c of the top plate, a, in addition to clasping the book downwardand binding it against the edge of the bottom plate, d, serves also as acutting-edge, again st which the leaves ofthe book are torn off, andalso as a guidingedge for severing the leaves.

I do not wish to confine myself to the use of the fastener in connectionwith memorandum-V books, or in connection with double covers or sides,as it is equally applicable to backs or boards for holding blank-papertablets, bound sheets of writing-paper, and other packages of paper whenthey are provided with a recess or groove, h, in the bound end, and I donot, therefore, limit myself to the exact form of the fastener G hereindescribed, as any fastener which is adapted to receive the bound end ofthe memorandum-book D, or other similar article, and hold it through theconnection it forms with it by means of the recess h, can be used inplace of the specific construction of fastener shown.

kthe cover A, of the fastener C, provided with a top plate, a, and ribd', and the book D, provided with the recess h, substantially asdescribed.

5. As a new article of manufacture, a book, D, provided with a channelor groove,.h, on one side only, saidr groove having parallel sides andclosed ends, to adapt the said book to be applied to and held by asuitable fastener, in the manner substantially as described.
